Summary based on the NamUs case record (MP17650) and 6 other sources
Raymond Guy Kung, a 24-year-old male of Filipino descent, was last seen on March 9, 1981, at his home in San Francisco, California. He has not been heard from since that day, and very few details have emerged regarding his disappearance. At the time, he was wearing a bright green t-shirt and black pants. Raymond stood 5'8" tall, weighed around 155 pounds, and had black hair and brown eyes.

Despite efforts from law enforcement, his case remains unsolved. There are no known leads or significant updates, and the San Francisco Police Department continues to investigate the case as an endangered missing person. His dental records are available, but no other identifying information, such as fingerprints or DNA, has been recorded.

Anyone with information is encouraged to contact the San Francisco Police Department's Missing Persons Unit.

Last Seen: Mar 9, 1981
